Review Meta AnalysisNonsteroidal anti-inflammatory drugs (NSAIDs) versus opioids for acute renal colic.
Renal colic is a common cause of acute severe pain. Both opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) are recommended for treatment, but the relative efficacy of these drugs is uncertain. ⋯ Both NSAIDs and opioids can provide effective analgesia in acute renal colic. Opioids are associated with a higher incidence of adverse events, particularly vomiting. Given the high rate of vomiting associated with the use of opioids, particularly pethidine, and the greater likelihood of requiring further analgesia, we recommend that if an opioid is to be used it should not be pethidine.

Review Meta AnalysisTopically applied anaesthetics for treating perineal pain after childbirth.
Perineal trauma is a major problem affecting millions of women around the world each year. The degree of perineal pain and discomfort associated with perineal trauma is often underestimated. Pain often interferes with basic daily activities for the woman such as walking, sitting and passing urine and also negatively impacts on motherhood experiences. ⋯ Evidence for the effectiveness of topically applied local anaesthetics for treating perineal pain is not compelling. There has been no evaluation for the long-term effects of topically applied local anaesthetics.

Review Meta AnalysisMegestrol acetate for the treatment of anorexia-cachexia syndrome.
Megestrol acetate (MA) is currently used to improve appetite and to increase weight in cancer-associated anorexia. In 1993 MA was approved by the USA's Federal Drug Administration for the treatment of anorexia, cachexia, or unexplained weight loss in patients with AIDS. The mechanism by which MA increases appetite is unknown, and its effectiveness for anorexia and cachexia in neoplastic and AIDS patients is under investigation. ⋯ This review demonstrates that MA improves appetite and weight gain in patients with cancer. No overall conclusion about quality of life (QOL) could be drawn due to heterogeneity. The small number of patients, methodological shortcomings and poor reporting have not allowed us to recommend megestrol acetate in AIDS patients or with other underlying pathologies.

Review Meta AnalysisEarly introduction of lipids to parenterally-fed preterm infants.
Lipids are essential components of parenteral nutrition for preterm infants. Parenteral lipids can be administered through a peripheral vein, and their early introduction offers the potential advantages of increasing energy intake and providing essential fatty acids and fat soluble vitamins. Concerns have been raised about potential adverse effects including chronic lung disease (CLD), increase in pulmonary vascular resistance, impaired pulmonary gas diffusion, bilirubin toxicity, sepsis and free radical stress. ⋯ No statistically significant effects of 'early introduction' of lipids on short term nutritional or other clinical outcomes, either benefits or adverse effects, were demonstrated in the studies reviewed. Based on the currently available evidence, 'early' initiation of lipids (

Review Meta AnalysisAntibiotic treatment for Clostridium difficile-associated diarrhea in adults.
Clostridium difficile (C. difficile) is recognized as a frequent cause of antibiotic-associated diarrhea and colitis. ⋯ Current evidence leads to uncertainty whether mild CDAD needs to be treated. Patients with mild CDAD may resolve their symptoms as quickly without treatment. The only placebo-controlled study shows vancomycin's superior efficacy. However, this result should be treated with caution due to the small number of patients enrolled and the poor methodological quality of the trial. The Johnson study of asymptomatic carriers also shows that placebo is better than vancomycin or metronidazole for eliminating C. difficile in stool during follow-up. If one does decide to treat, then two goals of therapy need to be kept in mind: improvement of the patient's clinical condition and prevention of spread of C. difficile infection to other patients. Given these two considerations, one should choose the antibiotic that brings both symptomatic cure and bacteriologic cure. In this regard, teicoplanin appears to be the best choice because the available evidence suggests that it is better than vancomycin for bacteriologic cure and has borderline superior effectiveness in terms of symptomatic cure. Teicoplanin is not readily available in the United States, which must be taken into account when making treatment decisions in that country.
